Application led November 20, 1922. Serial No. 602,128.

Be it known that l, Lnsmn Town, a sub ject of the King of Great Britain,.residing at No. 155 Earlham Grove, F oresty Grate, London, England, have invented a Means for Holding Abrasive, Polishing, or like Material, of which the following is the speciii'cation.

The object of this invention is to provide better` means than have hitherto been de# vised for securely holding abrasive or polishing or like material upon a handle or bar or the like means for operating the said material.

And in order that my invention may be completely understood refe-rence should be made to the accompanying sheet of drawings which illustrates the preferred form of construction. 'y

Fig. l is an elevation or edge view of the new tool.` n

Fig. V2 is a plan of same.

Fig.V 3 is a view with the handle. detached and with the abrasive material loose.

Fig. 4 shows the handle and taperthereon.

F 5 isa section showing a casing having a concave face for the abrasive'.

' Fig.l 6 showsa similar section withl a 'conveX face.

Fig. v7,y shows a knob on the adjustable L-piece to be' gripped bythe. left hand in operating the implemen part of its length and is also of tapered form on its interior. The front face of the casing has a true orplane surface upon which is adapted to be stretched or securely held the abrasive material B such as emeryl cloth. One end of the abrasive .material is folded insidethe casing and is clamped in position by the handle C `which may be made of wood or any other suitable material and which is formed with a correspond# ing taper to that of thek interior of the casing. The handle removed from the casing is shown at Fig. 4 which figure also shows a suitable degree of taper C for the handle. vWhen the abrasive material is folded within the casing the taper of the handle is pushed into the casing until it tightly tits therein, and thus grips the end of the abrasive material, the indicated in Fig. 3, tig tly between the tapered handle and the casing. The other end of the strip of abrasive material is secured The casing A is hollow for the greater osition of which is- `to the casing by means of the projecting stud D which is rigidly secured in the'back of thev casing. The end of the strip is clamped between the angular metal plate E and the plate F by means of the screws E E2. The plate F is formed with a longitudinal slot F which tits over thev stud D. The base of the stud has a rectangular head D which head is a sliding fit in the slot F and prevents any possibility fof the plate F turning upon the stud D. A nut D2 with a milled head has a thread fitting the stud? D and has a washer D8 `fitted between the nut and the plate F.

W hen the abrasivematerial is secured by the tapered handle C as before described, and has been clamped between l the L-plate E and the plate F by the said screws, the strip of abrasive niiaterial is pulled tight over the end of the casing by gripping theplate E and the nut D2 withr the washer is then screwed home upon the plate F to hold the plates E and F in position upon the back of the casing A,thus securing the abrasive material B in its stretched condition upon the face of the implement ready for use. i

Referring to Fig. 3, this shows the abrasive material loosein -position* on the casing ready for the ltapered handle shown in Fig.- 4 to be fitted therein and for the abrasive material to be tightened at the other end of the casing on the nut D as before described.

Fig. 5 shows a section of a casing A -having abrasive material B secured on a concave face in order that the abrasive material may be used ona rounded or curved surface of work. I

Figli shows a section having a. casing with a convex face adapted to be used upon a concave surface of metal. l

While thefcasing A with the strip of abrasive or polishing material'fsecuredthereto, may be held by one hand by the handle C, provision is also made for gripping the holder'at the other end thereof by the otherhand of the user, and for this purpose a knob or the like may be' provided at the outer or projecting end of one of the clamping plates that forms part of the clamping and securing mea-ns for one end of the abrasive Vor polishing strip at one end of the holder or casing, as illustrated in the modied construction Figure 7 of the drawings in which one of the clamping members designated E is provided with a knob or handle part E3, said knob or handle part E3 being adapted to be gripped and receive the pressure of the left hand in usine' the implement.

Bv the special construct-ion and arrangement-.ot parts hereinbetore described. means of a simplel efficient nature is a florded whereby the flexible strip polishinroY or abrasive material can be securely held on the` 't'ace of the holder or casing. The strip securiin means at one end of 'the holder or casing is readily adjustable, said means providing 'for adjustably tightening as well as securing' at one en(` said strip upon the vlace of the casing' or holder. Y
